What existing cladding and wall records, proposed brick product and system type should be identified before treating brick as a siding substitution?
Identify what is there and what is proposed
Use available plans, siding or remodel records, invoices, and ground-level photos to record the current cladding, any known wall repairs or leaks, and the areas where the proposed work meets windows, doors, rooflines, corners, and the wall base. Do not climb, remove siding, probe the wall, or treat a photo as proof of what lies behind the cladding.
Ask each bidder to name the brick product and describe the complete proposed system in writing. Is it anchored masonry veneer or an adhered thin-brick system? What backing, support, attachment, and water-management components does the selected manufacturer document for that system? Which existing materials would remain, and what must be evaluated before they can be used as part of the proposed assembly? A product name or sample by itself does not answer those questions.
How do documented differences between anchored masonry veneer and adhered thin-brick systems change the support, attachment, substrate, water-management and opening-interface questions for qualified review?
Why the system type changes the review
The Brick Industry Association’s 2020 Technical Note 28A distinguishes anchored veneer, with foundation support, structural ties, and an airspace/drainage approach, from adhered thin brick, which relies on a specified backing, framing, and bonding/support assembly. The note says existing wood, vinyl, aluminum, or fiber-cement siding is not an accepted direct-bond substrate for adhered brick in that guide; removing cladding also does not establish that the sheathing beneath is suitable for direct bonding. These are scoped examples from that document, not a design for this house or current-code verification. BIA, Technical Note 28A: Adding Brick Veneer to Existing Construction (2020)
Ask the responsible design professional to identify the site information and product documents needed before the scope is finalized, and who will obtain and review them. The cited note is a conceptual reference, not a design or approval for this property.
Which property-specific approval, removal, legacy-material, inspection and documentation responsibilities must be resolved without assuming a universal permit or retrofit rule?
Resolve openings, transitions, and project responsibilities
Ask how the proposed wall system will meet the actual windows, doors, sills, roofline, corners, wall base, and other changes in plane. Have the bidder mark which interfaces are included in the design and work scope, which existing components will be retained or altered, and where further inspection is needed. Do not assume that a typical detail applies to the particular opening or that an existing water-control layer will remain suitable after a change to the exterior assembly.
Before removal or ordering, get clear responsibility for evaluating concealed conditions, existing support and attachment, water management, and any legacy material that may require separate review. Ask who will prepare the system design, who will check it against the actual property and proposed product documents, and who will determine what approvals or inspections apply in the property’s jurisdiction. Requirements vary by project and location; this guide does not decide whether a permit, inspection, hazardous-material survey, or structural review is required. Do not start demolition to answer those questions.
What should written alternatives identify about retained, removed or modified parts, support, interfaces, water management, inspection, finish, maintenance, exclusions and unresolved conditions?
Compare complete written alternatives
Ask each bidder to identify, in comparable terms:
- the exact brick product and system type, and the documents used to define the assembly;
- what cladding, backing, trim, openings, and other components are retained, removed, or modified;
- the proposed support and attachment scope, water-management approach, and treatment of windows, doors, roofline, corners, base, and transitions;
- who is responsible for design, property-specific assessment, approval and inspection questions, removal, protection, and any further investigation;
- finish, care and maintenance documents, applicable product and workmanship terms, exclusions, allowances, and conditions that could change the scope.
Have the bidders list assumptions and unresolved inspections separately instead of burying them in a broad “replace siding with brick” description. Compare proposals only after the responsible parties have identified the same project boundaries and the assemblies they actually propose. If support, backing, water-management interfaces, or concealed conditions remain unresolved, defer the final selection and installation decision.
